I want to be able to get a PHP script called via AJAX to return with an error code that the jQuery AJAX handler error:
will handle. I don\'t want to use a JSON
Ajax transmission does not have to be JSON. It can be xml, json, script, or html. By default AJAX uses XML (the X from AJAX stands for that). I see that you are using jQuery. If you are using ajax method you have a dataType parameter that you can modify.
As you speak of it JSON is one of cleanest in my opinion, but if you mean simple you can use text instead.
